Bug Description

Mangler "seems" to stay up longer if I do not use it to transmit my voice, but use it to only listen, though it does still crash. Crashes happen 1-5 times an hour, most often when I key to speak, but not always. Sometimes the Mangler window 'grays out' and it will state that it has crashed, ask if I want to leave it closed or relaunch it, other times Mangler will simply close on its own. Sometimes it knows it crashed and says so very quickly, other times it will say nothing until I click to close it, when I click to close it, it does not always pop up the Leave Closed/Relaunch dialog box.

Text from the console from different crashes:

I have tried using both ALSA and Pulse, both crash at roughly the same rate. I ran Memtest 86+ for twelve passes, no errors.

I am not a trouleshooter, programmer, scripter, or otherwise tech-type person, but if you give me clear, step by step instructions, I will be more than happy to follow them in order to provide more information.

Do people still see these problems with mangler 1.2.5-1? I have crashes form time to time but am not sure if the same reason applies.

Mine is still crashing, but I am wondering if it is not the audio driver for my sound card, since I have sound issues with World of Warcraft as well. *Shrugs*

not getting a segfault, but the symptoms seem similar -- program wedges hard, window stops redrawing.

Ran the program with `strace mangler 2>/tmp/strace.log` and here's the last system calls:

futex(0x98534cc, FUTEX_WAIT_REQUEUE_PI_PRIVATE, 1, NULL, 0x985c528) = 0
clock_gettime(CLOCK_MONOTONIC, {1026549, 424232054}) = 0
write(17, "W", 1) = 1
clock_gettime(CLOCK_MONOTONIC, {1026549, 424536702}) = 0
write(17, "W", 1) = 1
futex(0x985c528, FUTEX_UNLOCK_PI_PRIVATE, 159724744) = 0
futex(0x98534cc, FUTEX_WAIT_REQUEUE_PI_PRIVATE, 3, NULL, 0x985c528) = 0
futex(0x985c528, FUTEX_UNLOCK_PI_PRIVATE, -1242918912) = 0
mmap2(NULL, 8392704, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS|MAP_STACK, -1, 0) = -1 ENOMEM (Cannot allocate memory)
write(2, "\n(mangler:11131): glibmm-CRITICA"..., 195
(mangler:11131): glibmm-CRITICAL **:
unhandled exception (type Glib::Error) in signal handler:
domain: g_thread_error
code : 0
what : Error creating thread: Resource temporarily unavailable

) = 195
futex(0x9436900, FUTEX_WAIT_PRIVATE, 2, NULL

... and that's where the program waited until I gave it a Ctrl-C. No troubles with the other programs (GTK+ and not) running at the same time, so I'm confident it's not some resource pool for the entire workstation being exhausted since the other GTK stuff doesn't crash nor hang.
